Osteosarcoma (OS) has an unfavorable prognosis and tends to metastasize to lung tissue. Although the CXCL12-CXCR4 axis appears to affect progression and metastasis in numerous tumors, its mechanism and downstream pathways in OS remain unclear. We used western blotting and flow cytometry to detect CXCR4 and CXCR7 expression in two OS cell lines (LM8 and Dunn). An MTT assay was used to evaluate t...
T has been knolwn to ecologists for some time that the commensal house mouse, I Mus muscuhs, has rather limited range of movement and that the mouse populations in different buildings are isolated from each other [see BLAIR (1953) for review]. It was also known that the different local groups differed in the frequencies of some genetically controlled traits (WEBER 1950; DEOL 1958; DUNN 1957). T...
It has been known for several years that deoxyribonucleic acid may normally contain 5-methylcytosine (Wyatt, 1951), 5-hydroxymethylcytosine (Wyatt & Cohen, 1953), and 6-methylaminopurine (Dunn & Smith, 1955, 1958a) in addition to adenine, guanine, cytosine and thymine. The first evidence of such additional bases naturally present in ribonucleic acid is the recent isolation of an unidentified nu...
